. ing Systems, of which the following is a of parts,

specification.

My invention relates to improvements in heating systems, and moreparticularly to that type or class in which the hot air is positivelycirculated or forced from the source oi heat or combustion chamber intothe heat distributing pipes or laterals through the medium of suitableair pressure pipes or nozzles communicating with a suitable air pressurechamber and a suitable tan or the like adapted to circulate the air intothe chamber and through the nozzles into the heat distributing pipes orlaterals.

The invention further relates to an improved flame enclosinggenerator-casing pro vided with heat distributing pipes or lateralsleading to the respective rooms or parts of the building structure to beheated together with an improved construction and arrangement of heatgenerating and air pressure circulating units, the air pressure unitadapted to provide a forced circulation of the hot air being preferablyprovided with air distributing laterals or nozzles arranged above theheat generating unit and being preferably arranged in alinement with andadapted to discharge hot air through the heat distributing pipes orlaterals whereby the hot air (and products of combustion arising fromthe burner where a burner is used) is carried through said distributingpipes with the air discharged therein by said air discharging nozzles orlaterals.

The invention further relates to the particular construction of the heatgenerating and air distributing units together with various cooperatingfeatures as will hereinafter more fully appear.

Vith the above mentioned and other ends in View, the invention consistsin'the novel construction, arrangement, and combination hereinafterdescribed, illustrated in one of its embodiments'in the accompanyingdrawings, and 'parti ularly pointed out in the appended claims.

Referring to the drawings, forming a part of this specification, Figure1 is a side elevation of a heating system constructed in accordance withthis invention, the heat gen erator casing and burner and air pressuredistributing heads, being shown partly in central vertical section forthe purpose of clearer illustration of the parts.

Similar numerals oi reference designate like parts throughout all thefigures of the drawings.

The improved apparatus carrying my improved heating system into effectcomprises a suitable generator or flame enclosing casing 1, which may beof any suitable and convenient form, as for example,of round. orcircular form, as shown in Fig. 1, and comprising a main casing 1, and aremovable bottom sect-ion 1, the sectional and 1 being preferablyprovided with flanges adapted to be detachably connected together bymeans of bolts 1 and nuts 1.

As a convenient means of suspending the flame enclosing casing 1 fromthe first floor 2, of the building to be heated, suitable hanger rods 3,may be provided, said hanger rods 3 being connected to suitable parts ofthe building and connected to lugs 1 of the main casing section 1.

As a means of supporting combustion within the generating casing 1 wherea gas burner 4c, is provided, the bottom section 1 is provided withsuitable air inlet openings 1 and as a means of properly distributingthe hot air or products of: combustion from the generator casing 1, thelatter is preferably provided with heat discharge ports 1, suitablyarranged and of a suitable number, to meet the number of rooms to beheated, said heat discharging ports 1 being preferably formed by meansof stub pipes 1 adapted to be connected to a suitable number of heatdistributing pipes or laterals 5, the latter being adapted to lead tosuitable register casings or boxes 5, promain casing l and and having acentral opening ided with suitable floor or wall as maybe required.

As a means of further promoting combustion (where a gas burner is used)and particularly as a means of accelerating and promoting the passage orcirculation of hot air through the heat distributing ports 1 and pipes'5, an air pressure distributing head 6, is mounted above the heatgenerator or burner, said distributing head 6 being preferably ofannular form, as shown, to provide air-annular air pressure chamber 6,

6 for the escape of heat, and the waste products of combustion from thesubjacent burner pass upwardly into the flue openings 1 of ing andthence upwardly into the flue i The air pressure distributing head 6 isprovided with a suitable air conduit pipe 6,

registers leading 'to a suitable source of air pressureas for example, afan or the like, operated by means of a suitable motor (notshown), saidair conduit pipe being preferably supplied with air from the exterior ofthebuilding to be heated. v

The air distributing head 6 may be mountedon lugs 1 extending inwardlyfrom the such head 6 is preferably provided with'a ba-flle plate 7,mounted on suitable supporting member 7, saidbaflle plate beingpreferably of disc shape, as shown, and being adapted to divert the heatand products of combustion outwardly toward the air' distributing pipesor'nozzles 6 of the head 6. The air distributing laterals or nozzles 6are preferably arranged in vertical central alinement with the heatdischarge ports 1 (see Fig. 2) and are adapted to discharge airseparately through the heat discharge ports and into the lateral heatdistributing pipes 5 whereby the heat arising from the heat source iscarr ed through said lateral pipes with the air discharged therein bysaid air distributing pipes or nozzles 6 communicating with the airpressure chamber 6 of the head 6.

. I If desired, an electric heating element such for example as suitableelectric resistance coils 8, may be mounted directly within the airpressure distributing head 6, as shown in Fig. 3 of the drawings, and asimilar arrangemen't may be providedlor use in the lower portion of thegenerator casing in lieu of the gas burner 4.

If desired the generator or flame enclosing'casing'l may be of elongatedform as at 1 as shown in Figs. 4' and 5 of the drawings, in whichinstance the gas burner may be in the specific form of a pipe burner land the air pressure distributinghead may be in the specific form of adistributor pipe 6 provided with nozzles or laterals 6 arranged inlongitudinal alinement and arranged in corresponding alined and arrangedheat discharging laterals or pipes 1 the caswhat I claim and desire tosecure by Letters- Patent is, i
